INVALID-BED.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed November 17, 1909. Serial No. 528,512.

T0 all 'whom it may concern: n

Be it known that we, JOHN A. GosNELL and JOHN OLSON, citizens of the United States of America, residing at Bradley, in the county of Kankakee and .State of Illinois, have invented new and useful Improvementsin Invalid-Beds, of which the following is a specication.

This invention relates to invalid beds, and one of the principal objects of the same is to provide a bed in which the mattress can be conveniently removed and replaced by an operating table, means being employed for supporting the patient during adjustment of the mattress or operating table carrying frame.

Another object of the invention is to provide a combined operating table and bed in which the mattress and spring-supporting device can be raised and lowered by vmeans of a crank and worm mechanism at the foot of the bed and in which a pillow support is provided having means for holding it in adjusted position.

The above mentioned and other objects are attained by the construction, combination and arrangement of parts, as disclosed on the drawings, set forth in this specification, and particularly pointed out in the appended claims.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate -similar parts in thev several views:Figure 1 is a side elevation of our improved invalid bed. Fig. 2 is a plan view of the same. Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1, looking in the direction indicated' by thearrows. Fig. 4 is an end view of the headportion of the bed showing the manner of adjusting the pillow support. Fig. 5 is a view similar to Fig. 1 showing the bed in use as an operating table. Fig. 6 is a section taken on the line 6 6 of Fig. 5. Fig. 7 is a section taken on the line 7-7 of Fig. 5. Fig. 8 is a detail side elevation of a slightly modified form of our invention.

Referring to the drawings, the numeral 1 designates the corner posts of the bed. Connected to the corner posts are the side rails 2 near the lower end thereof, and at the head and foot cross bars 3 and 4 are provided. Side rails 5 are secured to the corner posts at points near the upper ends thereof, and

connected to the outer sides of said rails are knobs or buttons 6 to which are detachably connected supporting strapsv or bands 7, but- .,tonholes preferably being employed at the ends of the straps for receiving the said knobs. The bands 7 serve as means for supporting a patient during the time of removing the mattress and substituting therefor the operating table or Vice versa. A pillow rest is pivotally mounted upon the rails 5, said rest comprising outwardly bent end portions 8 which pass through openings in the side rails 5 and a body portion 9 of yoke form. .Connectedto one ofthe corner posts 1 is a rack bar 10 designed for the purpose of engaging one of the side arms of the yoke for holding the pillow support in its ad-l justed position.

A flat metal brace bar 11 is connected to the foot corner post, and a similar bar is connected to the front corner post. An upright 12 is connected to the last named bar and to the cross bars 3 and 4. A similar upright 13 is connected to the foot of the bed. A shaft 14 is mounted in the bars 11, said shaft extending lengthwise of the bed at a point near the lower ends of the corner posts and disposed preferably at one side of the center of the bed. Mounted on said shaft at one end is a worm ear 15. A shaft 16 mounted in brackets 1 extends across the foot of the bed and is provided with a worm 18 to engage the worm gear 15. A crank 19 is fitted tothe end of the shaft 16 and is provided with an operating handle 20. Connected to the shaft 14 is an arm or link 21. At the opposite end of the shaft 14 is a similar linkf22. Connected to the link 21 by means of a bolt or pivot 23 is a lever 24, said 'of the spring frame 31 are mounted to rotate.. By means of the angular offsettrunnions the spring frame 81 occupies a position normally above the bearings 29 and may occupy a position below said bearings,

1oo l so that the angular trunnions provide means whereby theelevation of the spring frame may be varied. The frame 27 is provided at,

its ends with pivoted supports 32 upon which are formed ngers 33 which are adapted to be actuated to lie immediately beneath the side edges of the frame 31 to hold it against pivotal movement. rlChese lingers are located near the ends of the frame 3l so that they can 'be moved upwardly againstthe ends of the frame when it is desired to obtain angular adjustment of the frame. The bearings 29 are provided with set screws 34 which are'adapted to be engaged with the trunnions 30 to hold the frame 31 in its adjusted position. The construction is such that the mattress of the bed can be removed andan operating table substituted therefor. At the time of such removal ot the mattress the patient to be operated upon can be conveniently 'supported by the straps 7. After the operating table has been substituted for the mattress the apparatus may be actuated to move the operating table immediately beneath the -supporting straps, after which the straps can be disengaged from the side rails 5 to permitthe patient to be positioned immediately on the table. By pivotally supporting the frame 3l it is obvious that the operating table can be held at any angle.

In the modified form of our invention shown in F ig. S, the trunnion 35 of the frame 31a is provided with a pinion 36 which meshes with a pinion 3'?. The shaft 38 upon which the pinion 37 is supported has secured thereto an operating handle 39 whereby the pinion 3? canbe revolved and motion imparted to the pinion. 36. A pivoted dog i0 is operatively connected with the pinion 37 to hold it in its adjusted position. A

We claim v l. An invalid bed comprising` head and foot posts, rails connecting said posts, vertical guide vrods disposed'at each end of the bed between said head posts and said foot posts, a vertical .adjustable frame slidably mounted upon said guide rods, bearings depending from the sides of the adjustable frame, a mattress support disposed within said adjustable frame, angular offset trunnions provided upon said mattress support and journaled in saidbearings, anadjusting screw threadedl in lsaid bearings and adapted to engage said trunnions, and means to raise and lower said adjustable frame.

2. An invalid bed comprising a head and foot posts, rails connecting said posts, a bar connecting the head osts, a bar .Connecting the foot posts, a sha t having its ends supported upon said bars, a guide rod vertically disposed between said head posts and, also, between said foot posts,slides movable upon said guide rods, a frame supported by said slides and movable therewith, a worin carrying shaft transversely mount-ed upon one end of the bed, a worm gear mounted upon said first mentioned shaft and meshing with said worm, angular levers pivoted at one end to said slides, a level` arxn rigid with lirst mentioned shaft and connected to the free end of the angular levers, and means to impart motion to the transverse shaft whereby said frame may be raised and lowered.

in testimony whereof we aiiix our signatures in presence of two witnesses.
